Th e somatometric features from 80 Chinesepatients were used gender, age, height, body mass index, body surface area, trans-pyloric plane. Moreover, the aortic length from the origin of left subclavian artery to the orifi ce of the celiac trunk (LSA-CT) measured from tomographic scan examination. Th e variables to predict the length from the LSA-CT were studied in four types of predictive statistical
Th ere were 59 males (mean age 53.9 years SD 13.2, height 170.8cm SD 4.0) and 21 females (mean age 58.7 years SD 7.8, height 160.2 cm SD 6.8). LSA-CT distance was found to be 279.5 SD 31.34 mm. Th e length of distance from the jugular notch to trans-pyloric plane was 273.8cm SD 12.5. Th e body mass index was 25.6 Kg/m2 SD 3.8 and the body surface area 1.8 m2 SD 0.1. Th e tree model for predicting the distance to the left subclavian artery to the celiac axis was chosen due to obtained an R2 square of 0,829. Th e comparison between the tomographic values and results of the tree model was realized with a nonparametric test. Wilcoxon signed-rank test showed that the values of computed tomograhy scan did not show a statistically signifi cant diff erence with the results of the tree model (Z = -0.827 p =0.408).
